!check [amount of keys] : This command checks how many sets you can get by the amount.

F.A.Q :

Why i cant trade with bots ? Make sure your profile is not private and no trade hold on it.

Will I receive sets that I already crafted ? No, the bot will check your badges and only trade you sets that you never crafted.However, you may use the !buyany command to buy sets that have been crafted.
